WSM Polaris Piston Kit Oversize

The WSM Polaris Oversize Piston Kit line gives you replacement pistons for rebuilding Polaris engines with rebored or re-sleeved cylinders. Oversize pistons restore proper piston-to-wall clearance after the cylinder is machined. That helps bring back compression, power and reliable running in ATVs, UTVs, personal watercraft and other Polaris powersports engines.

Key Features:

• Oversize piston designs for engines that need a cylinder overbore during a rebuild
• WSM's forged piston construction for strength and durability
• Piston kit packages designed for engine rebuilds
• Available in multiple oversize steps to match the amount your cylinder is machined
• From WSM, a long-established maker of powersports engine rebuild components

Each part number in this line is specific to an engine and oversize step. Choose the variant that matches your engine and your cylinder's finished bore. A piston kit is a cost-effective way to refresh an engine's top end and get dependable performance from your Polaris machine.
